Reference
• If the laser marker transmitted negative response to the request data, all the contents instructed by the request data will
be invalidated.
• If the response code is "01", "02", "04", or "05", the command part will be returned as "???".
Response code details
The error cause is displayed in two numerical characters in case of invalid request data format or invalid value specified, or
when the laser marker cannot accept the request data.
Sub response code details
The sub response code indicates which data item is incorrect in case of an error with the variable-length or fixed-length
data part of the request data using a numerical value from 01 to 99 that represents the data sequence.
This value starts from 01 and increments by 1 from the beginning of the variable-length or fixed-length data part of the
request data.
If the data number exceeds 99, it returns 99.
Return 00 as the sub response code for the response code when the sub response code cannot represent the data item
sequence.
